具体代码如下所示:
<el-menu :default-active=‘$route.path‘ :router=‘true‘ :unique-opened=‘true‘ :default-openeds=\"defaultOpeneds\" background-color=\"#bd1e22\" text-color=\"#fff\" active-text-color=\"#ffd04b\"> //router当导航激活时允许以index作为路由进行页面的跳转,$route.path当前路由对象的路径,字符串,绝对路径 //unique-opened只允许有一个下拉菜单处于打开的状态 //使用default-active来实现当前菜单激活的选项 //default-openeds当前打开的 sub-menu 的 index 的数组 <el-menu-item index=‘/home‘>首页</el-menu-item> <el-submenu> <template slot=\"title\"> <i class=‘‘></i><span>导航一</span> </template> <el-menu-item index=‘/first/page1‘> <template slot=\"title\"> <i class=‘‘></i><span>选项一</span> </template> </el-menu-item> <el-menu-item index=‘/first/page2‘> <template slot=\"title\"> <i class=‘‘></i><span>选项二</span> </template> </el-menu-item> </el-submenu> </el-menu >
mounted(){ let path = this.$route.path; this.navConfig = [ {index:\'1\',path:[\'/system/aa\',\'/system/bb\',\'/system/cc\']}, ]; let thisNav = this.navConfig.find(item =>{ return item.path.includes(path); }); this.defaultOpeneds = [thisNav.index]; }
ps:下面看下vue Element-ui el-menu 左侧导航条
<template> <!--实现左侧导航条动态渲染(三级)--> <el-menu class=\"el-menu-vertical-demo\" @open=\"handleOpen\" @close=\"handleClose\" :collapse=\"isCollapse\" router unique-opened background-color=\"#545c64\" text-color=\"#fff\" active-text-color=\"#ffd04b\"> <el-menu-item index=\"/home/main\"> <i class=\"el-icon-document\"></i> <span slot=\"title\">首页</span> </el-menu-item> <el-submenu v-for=\"(item,index) in content\" :key=\"item.id\" :data=\"item\" v-if=\"item.children.length>0&&item.level==1\" :index=\"item.linkname\"> <template slot=\"title\"> <i class=\"el-icon-location\"></i> <span slot=\"title\">{{item.linkname}}</span> </template> <el-submenu v-for=\"(child,seq) in item.children\" :data=\"child\" v-if=\"item.id==child.parentid&&child.children.length>0&&child.level==2\" :key=\"child.id\" :index=\"child.linkname\"> <span slot=\"title\">{{child.linkname}}</span> <el-menu-item v-for=\"three in child.children\" :data=\"three\" v-if=\"child.id==three.parentid&&child.children.length!=0&&three.level==3\" :key=\"three.id\" :index=\"three.link\"> <span slot=\"title\">{{three.linkname}}</span> </el-menu-item> </el-submenu> <!--2无子级显示--> <el-menu-item v-for=\"(child,seq) in item.children\" :data=\"child\" v-if=\"item.id==child.parentid&&child.children.length==0&&child.level==2\" :key=\"child.id\" :index=\"child.link\"> <span slot=\"title\">{{child.linkname}}</span> </el-menu-item> </el-submenu> <!--1无子级显示且不支持点击事件--> <el-menu-item v-for=\"(item,index) in content\" :key=\"item.id\" :data=\"item\" v-if=\"item.children.length==0&&item.level==1\" :index=\"item.linkname\" :disabled=\"item.children.length==0 ? true : false \"> <i class=\"el-icon-setting\"></i> <span slot=\"title\">{{item.linkname}}</span> </el-menu-item> </el-menu> </div> </template> <script> import axios from \"axios\"; import $ from \'jquery\'; export default { data() { return { content: [], isCollapse: false, defaultProps: { children: \'children\', label: \'linkname\' } }; }, mounted(){ var _self = this; axios.get(\'https://5b90a18b3ef10a001445d08e.mockapi.io/api/v1/resources\') .then(function (response) { _self.content = returnZhData(response.data); }) .catch(function (error) { console.log(error); }); }, methods: { handleOpen(key, keyPath) { console.log(key, keyPath); }, handleClose(key, keyPath) { console.log(key, keyPath); }, handleNodeClick(content) { console.log(content); } } } function returnZhData(data){ var arrone=[]; $.each(data, function(index,one) { if(one[\'level\'] == 1){ arrone.push(one); var arrtwo=[]; $.each(data, function(index,two) { if(two[\'level\'] == 2 && two[\'parentid\']==one[\'id\']){ arrtwo.push(two); var arrthree=[]; $.each(data, function(index,three) { if(three[\'level\'] == 3 && three[\'parentid\']==two[\'id\']){ arrthree.push(three); } }); two.children=arrthree; } }); one.children = arrtwo; } }); return arrone; } </script> <style> .el-menu-vertical-demo:not(.el-menu--collapse) { width: auto; min-height: 400px; } </style>
